Following Christopher Nolan’s Dark Knight trilogy and The CW’s Arrow, another live-action Ra’s al Ghul is on the way.

FOX has confirmed that Gotham has brought in Alexander Siddig to play their particular take on The Demon. Siddig will be familiar to genre fans for playing Doran Martell in Game of Thrones, not to mention appearing as Dr. Julian Bashir in all seven seasons of Star Trek: Deep Space Nine.

When Gotham returns to screens next month, a major part of the show will be David Mazouz’s young Bruce Wayne digging deeper into the mystery of the Court of Owls – a mystery that will lead to Ra’s al Ghul.
